Working on this VR, I finally discovered how to lick a problem known as "banding" where radically different exposures or light values from one frame to another leads to graying and banding of that graying, in a section of the vr. To adjust for banding in this VR, 11 out of 16 exposures had to have their brightness and contrast adjusted in photoshop before stitching. It added several hours to the process but the results are worth it. Now, I have to find time to go back and redo some earlier ones that suffered from banding.....oh brother...a webmaster's day is never over.
Banding and mixed lighting are similar but not always the same. Mixed lighting can show itself when you shoot a full 360 degrees of any location, especially here in Hawai`i where trade winds blow clouds around so fast you're lucky to get 2-3 minutes of similar, consistent lighting anywhere. Some banding you can fix, mixed lighting you sometimes just have to live with.
For those of you who do VR's this one took almost five and a half hours to do, from shoot to finish. Several stitches were performed. I finally stitched this VR interactively so as to able to fine tune overlap of the exposures.
